Coworker Thinks I'm The Psychopath Texting His Wife & Himself ????‍♀️

I honestly don't know much...because I'm not the person harrassing this coworker & his wife, but he sure thinks I am ????

Things I have heard...

Coworker apparently receiving harrassing texts shortly after sending me work related emails.

Coworker's wife receiving (nasty) targeted texts related to (coworker's/husband's) travel and location.

Coworker apparently changed phones and phone numbers and I hear they are still receiving texts, with knowledge of their location and personal information.

Problem is...this coworker has waged a war against me, contacting my boss and the management of my organization accusing ME of this "personal text war" against his wife and himself. I don't believe any money requests have been made, so WTF could be happening here?

Also, how do I protect myself from my coworker's slanderous accusations?

Seems that this coworker has taken steps to hide his work travel plans and new phone number from most (especially me) work associates, but harrassing texts to them continue, and I'm still his main suspect.

I kinda think he or his wife may have targeted me for some reason. If this is true, it seems like a psycho " Lifetime Movie Network" situation. Help!!!

Anyone with hints, help, or suggestions for the next steps for me to prove my innocence or ideas as to what else could be happening here are appreciated. This BS has caused me an unbelievable amount of stress that has affected my mental, emotional, and mental well-being, so any thoughts, suggestions, or steps are appreciated. This could also cost me my job and has made the work environment (when he's in the physical office) a living nightmare.

My boss actually confronted me about this, and I of course told him the truth...it wasn't me. I also do not believe anyone in my office gives two 5hits about this coworker's life or wife to target them.

Also, this same coworker has requested a penetration test for our work network...I'm sure he thinks he's gonna find some proof that I'm the psycho anonymous texter, but once again...not me dude.

I need smarter people than myself to help me understand WTH may be going on, and how to stop this insanity that's been going on for nearly two years.

Oh yeah, hate to mention this but this coworker and his wife are apparently heavy drinkers...perhaps even binge drinkers? IDK their exact alcohol consumption schedule.

Coworker has been known for work travel blackouts due to alcohol...dude has three separately named personalities for his stages of inebriation that other coworker's have actually coined and joke about...or at least they used to.

Thank you for your assistance guys ????
